Prime Time Smile Active Blue Kit, $29.95 Blue light technology is fancy stuff. Dentists and dermatologists charge a premium for you to sit under a blue light while they tend to other patients (or check their Instagram feeds). But this patent pending at-home gadget is a game-changer. It works the same way, and you can buy it for a fraction of the price … at Walmart. It comes with two pens that contain a pre-treatment and whitening gel.
